In this derivative all I did was completely change the way the ball is supported and the size of the ball to make it detach easier and work more effectively.

I was only able to detach the ball in a few of my whistles from the original V2 version. If you were having those problems this is the whistle for you.

I also disliked the fact that the original poster did not include other formats that allow for editing, I have included IPT (inventor 2010), STP, IGS, and STL.
